Arroyo Seco Museum Science

Arroyo Seco Museum Science serves 428 students across kindergarten through eighth grade in Los Angeles. The school earns a composite score of 9.1 out of 10 — rated Exceptional — placing it 48th among 563 public schools in the city and in the top 2% of all public schools statewide. Academic and growth scores tell a consistent story: 9.0 on academics and 9.4 on growth.

A high growth score matters because it measures how much students advance year over year, not just where they start. At 9.4, Arroyo Seco students are gaining ground at an above-average rate regardless of incoming ability level — a mark that distinguishes schools that actively accelerate learning from those that simply serve higher-performing populations. Enrollment sits at 428 students with a student-teacher ratio of 20.4:1.

The school ranks 180th out of 9,533 public schools in California, a top-tier position for any urban K–8 campus. Parents comparing options across Los Angeles will find few regular public schools that pair this level of academic performance with consistent, measurable student growth. The school's scores place it among the strongest elementary programs in California by nearly every metric available.

The student-teacher ratio at Arroyo Seco Museum Science is 20.4:1, which is higher than the national average. This may mean larger class sizes, so parents should ask about classroom support, teaching assistants, and how the school differentiates instruction for students who need extra help.
